Descripción
Sumario:<div class="page" title="Page 1"> <div class="layoutArea"> <div class="column"> <p> <span style="font-size: 8.000000pt; font-family: 'Calibri'">Keplerates are a family of anionic metal oxide spherical capsules containing up to 132 metal atoms and some hundreds of oxygens. These capsules holding a high negative charge of -12 coordinate both mono-anionic and di-anionic ligands thus raising its charge till -42 even till -72, which is compensated by the corresponding counter-cations in X-Ray structures. We present an analysis of the relative importance of several energy terms of the coordinate bond between the capsule and ligands like carbonate, sulphate, sulphite, phosphinate, selenate, and a variety of carboxylates, of which the overriding component is the contribution due to solvation/de-solvation effects. </span></p> </div> </div> </div> <p> &nbsp;</p>
